...and who don't bother to look at the menu and consider what they want to order until they are supposed to be ordering.
Dude - we've been standing here for 10 minutes waiting to get to the front of the line. But you were so busy yammering on about something dumb you did last weekend to even bother to look at the menu. Your job is to figure out what you'll order while waiting and before it is time to order. Take care of that, then you can shoot the bull with your buddy.
